I didn't look at 16= 8+8 so I really did try to look at it upside down!

very clever. But are you not, as a technical matter, "changing" the equation when you turn it upside down?

surfer chick, have you gone to your personal physciatrist (however you spell that)

ymiroc, you're not turning it upside down, you're just LOOKING at it upside down, so therefore not changing the equation.
Nice teaser.

Yes but when I turned it upside down I dropped the monitor and now I can only get 253 colours!

Wow. I thought you turned the addition sign around for 8X8=91. It's technically not changing anything, because it's the same sign.

Good trick teaser.You tricked me.
AuthenticallyMe*
Aug 27, 2007

I thought it would be to turn the "=" sign around so it looked like a multiplication sign. I figured that I wasn't changing it, but merely reorienting the characters in the equation...turns out your answer was better and more clever! At least I was thinking about rotating the [part of] equation to get my answer...

very nice one in deed.made me think..

lilredc5*
Aug 27, 2007

simple, easy, and amusing. At first glance I thought 'come on, you have to change it at least little, even if the change is miniscule. But no I was wrong, don't need to change the equation, just need to change the reader of the equation. Hang from the ceiling perhaps.
mi2mo2tx*us*

VERY VERY clever! Got me! Thanks,
buckeyechris*us
Aug 27, 2007

Very clever but in fact you do change it when you look at it upside down. Utilizing that particular font, you have to flip the 1 around when you look at it upside down. Not to be negative but I was just using your rules to evaluate the problem and when I did that I got a 6 preceded by a figure that sort of looked like a 1 when viewed upside down.

At first I thought (s)he was lying, but I was wrong!
buckeyechris*us
Aug 27, 2007

If you would have used the font, "Gill Sans MT Condensed" , then I agree with you otherwise I'm not in complete agreement with the answer.

OIC Upside down Huhhh
2ndhandroseca*
Aug 27, 2007

HI

I just turned the 91 upside down and got 8 + 8 + 16.

Why turn the whole thing over
Dunno.

I believe this is also correct unless
I need another Tea.

Someone let me know if I'm wrong.

THIS IS HOW TO SPELL "phsyciatrist" whoever was
rude & asked.

Rose again Sorry, I made a typo.
Turn the 91 upside down and
it becomes 8 + 8 = 16. not plus
16. Sorry OOPS

After I stood on my head and the blood rushed to my brain the answer made perfect sense. Loved this one, keep them coming. Thanks.

Aug 27, 2007

If you only rotate the 91, then you're changing part of the equation, which would be against the rules.

that was cool. good job

good one!! today was my first day of middle school and i have had problems like that before in elementary school so it was kinda easy... but it was really good!!!

Wouldn't it be more accurate to say "read it backwards??" But no biggie.

Pretty easy but fun!

"phsyciatrist" is spelled "psychiatrist"

Funny joke boodler!

This one had me laughing literally, out loud It was so "GOTCHA"! Thanks for Getting Me
Hungrygiten*
Aug 27, 2007

You can't just 'turn' the 91 upside down, because that is changing the equation. 'Looking' at the whole equation upside down doesn't change what is writenn and keeps the equation intact (even though, technically, it's a different equation).
I liked this one. If I bothered with favourites, this would be added to them,
Candygirl415Aus*
Aug 27, 2007

I got in a sec. just figured 8+8=16 so how do i get 16 out of 91... oh! it's upside down...lol
DewlannaSoloAus*

easy. especially late at night when my mind turns things upside down any way.

jennsingergirlAus*
Aug 28, 2007

Your instructions are incorrect. They need to say "How can you make the following equation correct without changing the numbers or symbols?" By flipping it over, you actually are changing it, so my suggestion would make your teaser more accurate.

I got it right!!!!! That was a great teaser. I liked it alot. Thanks for the post.

I was thinking 91 being 16 upside down but I didn't think about the whole thing being upside down! Fun teaser!

ymiroc: You are not changing the position of the equation, you are changing the position of your head. Or if you have a laptop like me u can turn your computer upside down.

Oh wow!

That was really clever! I never thought of that!

Excellent!!!

... But you changed it... By turning it upside down... Anyway, I still liked it a lot!
willymapo*cr*
Aug 27, 2010

Ok. For those that claim that turning the equation upside down is changing it, then try to read it hanging upside down. That way the one that changes is me!
kwelchansAus*
Aug 27, 2010

How about this: Stand on your head. That way, your not changing the position of the equation in any way, only the position of yourself!

Boy, some of you sure get caught up in the semantics. Cute, but very easy. Liked it.
davidrools*
Aug 27, 2010

No, it's still wrong, just upside down. It still says 8+8=91, unless you changed something ;). Still fun though!

Aug 30, 2010

I was thinking, that the you should just pretend that it is correct and move on...

Feb 28, 2012

I thought the answer was 'no'.

That was so very easy that you could figure it out by the time it took to read it.
gaylewolfAus*
Aug 27, 2013

It was a good one and it was fun, but I didn't get it quite as fast as YOU did, Babe!!
chibivampire123

That's cool
Turn it upside down becomes
16=8+8

A bit to easy.

Thought about it for awhile, then gave up - certainly was easy after I looked at the answer. I should have waited until morning when I was fresher! I really enjoyed it regardless
